FREDERICK ANTENEN, F HAMILTON, OHIO EGG-TESTER.

Applicationfiled AprillS, 1911. Serial No. 620,911,

To all whom it may concern: Be it known that I, FREDERICK ANTENEN, acitizen of the United States, residing at Hamilton, in the county ofButler and State of Ohio, have invented certain new and usefulImprovements inEgg-Testers, of which i the following is a specification.

to surround and inclose the globe or part of, the lantern from which thelight radiates,

in such a manner that the light may be confined within said mantle, onesection of said telescopic mantle having'an opening through which theeggs may be tested, and the parts,

of saidmantle adapted to be telescoped to expose the light on all sidesof the lantern to perform its functions as a lantern.

My invention also consists in constructing said telescopic cylindricalmantle in such a manner that the parts thereof may be readily telescopedrelatively to each other, in such a manner as to permit the same to beeasily and quicklyplaced inposition for use-upon a lantern and also maybe easily and quickly removed therefrom when it is desired to use thelantern without the egg tester in the usual manner.

My invention also consists inthe peculiar con'structlon, 'combmatlon Iand arrangement and in the darts: and combinationof'parts as herein setorth and claimed. I

In the accompanying drawing whlch servesto illustrate-the construction,application and use of my invention: Figure 1 1s a side elevation,showing the mantle in position on the lantern for use asan egg tester.Fig. 2 is a side elevation, showing the parts of the cylindrical mantletelescoping to expose-the light for use as alantern. Fig. 3 is avertical. section of the mantle in extended 'position. Fig. 4 is afragmentary sectional view on the line 4-4 of Fig. 3, showing the,partswhen telescoping or in the position shownin Fig. 2. Fig; 5 is atop View of'section 1 of Fig. 3. Fig- .is view partlyflin side elevationand partly-invertical section,,

showing the, arts in telescoping position i Specification of LettersPatent. Patented June 6,1911.

In the em odiment of myinvention. and

,which shows a preferredconstructiom A represents a. metalliccylindrical mantle or shield formed in two sections 1 and the;uppersection 1- being; adapted to telescope within the lower section- 2.The up'persection 1 is formed with a'n-inturned bead 3 upon its upperedge togivethec proper strength and finish to the structure, and isprovided withthe inwardlyextendingspring catches 4 secured to thefbodyof-the section by rivets 5 or otherwise, and having. their upper endsprojecting upwardly beyond the end of. the section. These spring catchesare adapted to take over andengage flange 6 of thelantern 7 ofth'e'usual construction. The lower section 2 ofthe mantleis providedwith a bead 8 at its upper ,end to give it the proper strength andfinish," said, bead being turned outwardly.

A vertical slot .9 is formed near 'tl1e top of section 2 and a springcatch. lOis'suitablyLsecured at its lower end to said section inalinement with said slot, said catch-being pro; vided with a projection11 normally extend ing through said slot, and the upper end of saidspring. catch projecting beyond the up per end of section 2 as clearlyshown ,in Fig.

4. A'slot 12 is providedfinthej end of section. 2' to allow theliftingfarm'li; ofthe laIi-i tern'7't0 enter to permit the sectionto bemoved to its lowermostposition, as'shown in Fig.1. The manner ofattachment of my device to a lantern and its method of 'use is asfollows: Telescope section 1 within section 2, tilt the globe 16 of thelantern to one side, place the mantle over .the sam'e hnd returnth'eglobe to its proper position in the lantern, then move section 1upwardly, pressing thev spring catches 4c outwardly until above theflange 6 of the lantern, when the springcatches should be released, andwill automatically spring into engagement with the upper edge of saidflange and hold said .section in proper position. If it is desired touse the device as an egg tester, section 2 should be moved downw'ardlytothe position shown in Fig. 1-, so that the opening 1% in section 2through which to examine the eggs will be oppositethe flame from theburner 15 of the lantern 7 When it is desired to use the lantern as alantern, move section 2 upwardly to the position shown in Figs. 2 and 4,allowing the projection 11 to spring over the upper edge of section L,and'thereby hold section 2 in its elevated position. To lower section 2again for the purpose of an egg tester, simply press outwardly on'thespring catch 10 to release the projection 11 and then move the section 2downwardly to the position shown in Fig. 1.

When it is desired to remove the mantle from the lantern, simply reversethe operation above described for placing it upon the lantern.

When it is desired to test the eggs with this device, simply light thelantern and placesections 1 and 2 in the position shown in Fig. 1,taking the device into a dark room or cover it and the operator with ablanket to form a dark place and place the eggs in front of the opening14, when the condition of the eggs will clearly appear to the operator.

One of the advantages of my invention is that I am enabled to combine inone useful article, a lantern of the ordinary construction, and aneiiicient egg tester, in such a manner that the lantern and egg testermay be used alternately to perform their separate functions, withoutremoving the egg tester from the lantern, and by simply adjusting theparts of the mantle in a convenient manner or- 'by' removing it entirelyfrom the lantern if desired.

Another advantage of my invention is that it is portable and may bereadily carried to wherever the eggs may be stored or located, thusavoiding the necessity of taking or carrying the eggs to the tester asis usually necessary. With the use of my invention an egg buyer maytravel from farm to farm and by means of this combined lantern and eggtester is provided with the necessary light for use under allcircumstahces and also with a strong light confined therein in such amanner that he may examine the eggs as he purchases them, regardless ofwhetherit is light or dark, by simplycovering the egg tester with a suchtions light and darkness for examining eggs to determine their conditionby looking through them from darkness into light.

Another adv-antage'of my invention is that I am enabled to use the samecylindrical telescoping mantle as a shield whereby I am enabled to use,the lantern as a heating device for use in vehicles or otherconveyances, said mantle serving as a shield to protect the clothing ofthe occupants of the conveyance, andt -also to assist in retaining theheat. 4

Other advantages will be apparent from an examination of the device.

Various modifications of my invention may be made without departing fromits spirit or scope and for this reason I do not wish to be confined tothe exact construction or arrangement of the parts as herein shown anddescribed, but ,What I claim and desire to secure by Letters Patent is:

1. In an egg tester, the combination with a lantern, of a telescopicmantle or shield having an opening therein, substantially as set forthand for the purposes specified.

2..In an egg tester, the combination with a lantern, of a cylindricalmantle formed in two sections, one of which is provided with an openingthrough which an egg may be tested, said sections being adapted totelescope relatively to each other.

8. In an egg tester, the combination with a lantern, of a telescopiccylindrical mantle formed in two sections, one of which is provided with"an opening through which an egg may be tested and spring catches on theother section adapted to detachably hold said. mantle in proper positionupon a lantern.

4. In an egg tester, the combination with a lantern, of a telescopiccylindrical mantle.

formed in sections, one section of which is provided with an openingthrough which an egg may be tested, said section having a slot and aspring catch having a PIOJECUOII adapted to extend therethrough andengage thetop oi the other section to hold the lower section in elevatedposition, substantiallv as" set forth and for the purposes FREDERICK AlVitnesses J Amps N.'RA1\ ISEY, WINONA DOAN.
